Blends of LLDPE and LDPE combine the favorable mechanical properties of the LLDPE with the ease of processing of LDPE. Yet, the melt rheological consequences of blending LLDPE and LDPE have received far less attention than have linear/linear or linear/ branched blends (1). Previous reports showed that blends of LLDPE/LDPE were either immiscible or partially miscible (2–5). Considering the compo...

Abstract The interactions and morphology of molecules in a polymer blend influence the physical properties blend. However, little is known about molecular interaction on thermal mechanical LLDPE/wax blends. Although cooling rate can be used to investigate blends' properties, it inadequate determine between since related blends could rate, samples prepared by melt mixing were cooled at different...

The manufacture of biopolymers foams with poly-lactic acid (PLA) and thermoplastic starch (TPS) using the green process of extrusion assisted by supercritical CO2 is a promising way towards new applications. A parametric study evidenced that the porosity is strongly correlated with the die temperature, CO2 content and TPS load. To get a high porosity, die temperature has to be diminished to blo...

Directional crystallization from the melt has been used as a tool to grow parallel crystalline stripes of p- and n-type molecular semiconductors. To start, phase behavior 2,7-dioctyl[1]benzothieno[3,2-b][1]benzothiophene (C8-BTBT-C8): tetracyanoquinodimethane (TCNQ) blends (molar ratio 20:1 1:1) investigated by variable-temperature X-ray diffraction, differential scanning calorimetry, polarized...

In the present study, the properties of polycaprolactone (PCL) and wood flour (WF) blends were examined by Fourier transform infrared (FTIR) spectroscopy, differential scanning calorimetry (DSC), Instron mechanical tester, and scanning electron microscopy (SEM). As for results, the mechanical properties of PCL were lowered obviously, due to the poor compatibility between the two phases, when it...

Using our simple lattice-based equation of state, we capture the effect of deuterium substitution in polystyrene (PS), predicting both the pure component melt properties and the remarkable shift in the coexistence curve when hPS is replaced by dPS in forming a blend with poly(vinyl methyl ether) (PVME). Taking advantage of a rare opportunity to compare with experimental pure component data, we ...

Hydrogel optimisation for biofabrication considering shape stability/mechanical properties and cell response is challenging. One approach to tackle this issue is to combine different additive manufacturing techniques, e.g., hot-melt extruded thermoplastics together with bioplotted cell loaded hydrogels in a sequential plotting process. This method enables the fabrication of 3D constructs mechan...
